Con respecto al problema sobre el billar de Sinái planteado la semana pasada, nuestro comentarista habitual Salva Fuster observa lo siguiente: “No resulta sencillo “cocinar” el problema para que se mantengan las medidas proporcionadas de manera aproximada. Si mantenemos 10 y 16 cm como medidas exactas, los rebotes previos ya no se producen como en la imagen. Si cambiamos el 10 por 9,37 cm, las medidas encajan bastante bien, quedando un cuarto impacto en la parte izquierda del perímetro del cuadrado a unos 11 cm desde la parte inferior y el quinto impacto en el círculo a unos 10 cm desde el inferior del perímetro cuadrado (a unos 220º si medimos el ángulo del círculo de manera convencional). Lo que está claro es que este billar es bastante caótico, pues ligeras variaciones en las trayectorias generan rebotes muy distintos”.
